Back in April this year we published an anonymous blog about bullying. It started like this:"It was 3.45 on a Friday afternoon. The tears came almost as soon as the bell sounded and quickly became those choking sobs that prevent words from coming out, let alone making sense."She sat at one of the desks where the PSHE lesson on bullying had just taken place and allowed the emotions to take over. It was clear that she had been holding them in for some time and the lesson content had triggered a reaction.Sarah was being bullied and had been for some time."

Most of us would jump to the conclusion that Sarah was a child, but we would be wrong, she was a teacher who was being tormented by a fellow member of staff.

Teachers, the people who are looked upon to drive home the anti-bullying message to the students in their care, can often be the victims of bullies themselves. Those bullies can be colleagues, leaders, parents or even pupils and they can have a devastating effect on a teacher's career.

In fact when we ran our first GTN survey we found that 90% of teachers had experienced bullying in the workplace and in June Education Guardian ran this story about NQTs being bullied out a job.

But our live chat, with our panel of experts, is designed to give teachers a heads-up the week before the official launch of Anti-bullying Week (Monday November 19 to Friday November 23) to offer tips, guidance and expertise that could help you tackle bullying in your school, whether it be the pupils or staff who are the victims.

There are many issues to explore. So join us on Thursday November 15, 4pm to 6pm for a live chat to debate how we can help to make bullying unacceptable for everyone. The discussion takes place on this page in the comments thread below is now open for your questions and thoughts - so please do add in your experiences and some tips and hints you would be willing to share about how you tackled bullying. You can also email questions, ideas and comments to emma.drury@guardian.co.uk

See you online on Thursday.
